Re: creating pages using the API [Our Ref:CPTEE8C7 Your Ref:CPTB3A81]

The ParamBean object tries to decode the URL, looking for certain 
parameters such as a page ID, current editing mode, etc... Basically try 
to generate an URL that would look like this :

http://localhost:8080/jahia/CreatePersonalHomePage/pid/3/op/edit

or something like that. When Jahia creates a page it needs to know the 
current page that will automatically become the parent page. Also, when 
creating a page you also need to create the "navigation container" that 
will contain it. All this is not trivial but has been covered in the 
various mailing lists before, I suggest you search for it.
